My 2 Ghz PowerPC G5 only recognizes one CPU.

Correct me if I'm wrong, but if I have a duel processor, shouldn't my hardware window under contents be showing "Number of CPUs: 2"? Right now it only shows "Number of CPUs: 1". This looks like a really bad thing, especially because I can't play really any of my Logic Projects anymore. Does anyone know how to troubleshoot this issue?

I don't know which 2GHz model you have, was this a late 2005 with PCI Express video and slots? It could then be dual core, single cpu.

When you bring up Activity Monitor in the Utilities folder, then, you only see one CPU usage graph when you click the "CPU" tab at the bottom? Not something like this:
If that's the case, we have a puzzle on our hands, since the diagnostics should report a failed CPU, I would think..
Just for kicks, in System Profiler, what is your information display? Copy down to just before the serial number, as in (my ancient machine)

Trying to use multiple Blue Snowball Microphones, but Mac only recognizes one!

Trying to record using multiple snowball mics by blue, but the Mac will only recognize one device at a time. Only one shows up in system preferences, and in trying to create an aggragate device. If you have both plugged in, the audio levels freeze up, and the devices become unresponsive.
I have seen similar threads around but no one seems to have any answers. Blue's tech support is closed for the weekend so I can't call them. Please help if anyone has any ideas.

Typically, over USB I can only get my computers (mac and PC) to recognize 2 channels at a time over one source. If your computer is recognizing one and not both or the other when both are plugged in, I think one is all you're going to be able to use. Also, in the system preferences under Sound, if you are able to only select one or the other, I believe all you can do is select which one you want to use.
Those micrphones work well and one should do a good job. Don't forget about Micrphone Phase Cancellation.

HT1670 Sync iPhone/Entourage will only recognize one of my two iPhones?

I have two iPhones. One I have managed to sync no problem, but the second is just not interested! A friend told me that with iPhone/Entourage will only recognize one iPhone, if so is there anything I can do to sync my second phone?

Hi, Darcie13.
Thank you for visiting Apple Support Communities.
If your device is not recognized by iTunes, I would recommend the steps in the article below. Start with the section labeled Verify that the Apple Mobile Device USB Driver is installed > For Windows Vista, Windows 7, and Windows 8 > If the Apple Mobile Device USB Driver is not listed.
iPhone, iPad, or iPod touch not recognized in iTunes for Windows

HT1430 iPhone only recognizes one home wifi network but ipad recognizes both

I have two home wifi networks. My iphone only recognizes one wifi which is the slower. Ipad recognizes both. I've turned router off and on and turned iphone off and on and makes no differences. Also ipad used to pick up unsecured wifi networks but no longer does
which I don't want but wonder why that suddenly changed

Hey Dann4ever,
I would follow these steps for when you're unable to locate a Wi-Fi network on your iOS devices:
Be sure you're in range of your Wi-Fi router (access point).
Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your W-Fi setting is dimmed, follow these steps.
Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
Restart your iOS device.
Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
Tap i and Forget this Network.
Try to connect to your desired Wi-Fi network.
Note: You may need to enter your Wi-Fi password again if your network requires one.
Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
Verify that the network is available by tapping Settings > Wi-Fi and choosing from the available networks.Note: It may take a few seconds for the Wi-Fi network name to appear.
Move closer to your wireless router (access point) and attempt to locate the Wi-Fi network.
If you do not see the network you would like to join, you may be attempting to connect to a hidden network. Learn how to join a hidden network.
Supported Wi-Fi configurations vary by iOS device model. Find out which standards your device supports3.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings
via: iOS: Troubleshooting Wi-Fi networks and connections

Are you using the same homesharing ID for both computers, are they on the same network.

Why only using one CPU

Just noticed when importing CD into iTunes on my MacBook is only uses one cpu, with activity monitor it show 98-100% CPU and never goes over 100%
My fans also run when importing, I use lossless.
Why not use more CPU speed?
R

I believe only applications writen to do so will take advantage of dual processors. I guess iTunes has not yet been updated for dual processor use.

HT1423 My imac G5 only recognizes one slot after installing 2x2 GB ram

My mac is a early 2009 model running 10.7 software. I realized it was running pretty slow so i decided to upgrade the ram from 2GB to 4GB. After installing it, i checked my memory and it recognizes one slot and not the other.

I swapped them and it showed that the other slot did not recognize it either.
Its the correct RAM for my computer, I contacted the seller and hopefully they would send me another. Thank you!

Multisim 11 only uses one CPU core during simulation

Hi,
Just recently I've been using MultiSim again, v11 if that matters, and simulating goes slow, to my opinion that is.
Now there are two things that I've noticed:
- Multisim only uses one of two CPU cores during simulation, not both;
- I've enabled CPU throttle (AMD's Cool'n'Quiet) but corespeed remains very low even though Multisim needs CPU power while simulating.
The simulating of a NE555-based LED-flash circuit requires about 28 seconds to get to 100ms in the simulation. Now if I can get the CPU to throttle up, by for example having Prime95 stress one of the two cores, then the simulation only requires 12 seconds to get to 100ms.
So here are my two questions:
1. Is Multisim 11 capable of using more than one CPU core while simulating? If yes, how can I get it to use more than one?
2. Probably not the right forum to ask, but is there a way to force Windows 7 Ultimate x64 to throttle up the CPU when Multisim starts simulating? Since Multisim does not seem to stress the only core it uses enough to throttle it up. Using Prime95 on one core does trigger a throttle up.
With regards,
Bart Grefte
Relevant specs:
Windows 7 Ultimate x64
Multisim v11
AMD A4-3400
16GB RAM

Completely forgot this topic....
Is there a good reason why there is no multicore support? Multisim can certainly use it for simulating.
As for the CPU throttling, I found a batch that can increase/decrease the "minimum processor state"-setting and it works immediately, no reboot required.
@echo off
powercfg.exe -getactivescheme > "%userprofile%\appdata\~apo.tmp"
set /p v_currentscheme= <"%userprofile%\appdata\~apo.tmp"
set v_currentscheme=%v_currentscheme:~24,36%
del "%userprofile%\appdata\~apo.tmp"
powercfg -setacvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -setdcvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -s %v_currentscheme%
exit
Usage is simple:
Start -> run -> c:\pathtobatch.bat 100
for "minimum processor state"-setting at 100%
Start -> run -> c:\pathtobatch.bat 5
for "minimum processor state"-setting at 5%
Please note that "set v_currentscheme=%v_currentscheme:~24,36%" is not the same for every language. The original batch had "set v_currentscheme=%v_currentscheme:~19,36%" (most likely for the English version of Windows 7), but since my Windows install is in Dutch, I had to change it in order for it to work.
Running the batch with @echo off removed will show why.

Ipad only recognizes one Apple ID

I have two Apple IDs with the same password. On the iPad, only one is recognized. Every time I try to sign in with the other, and type in the password, the iPad rejects it. Why is this?
I have some purchases on one ID, and some on the other, and that is why I have to sometimes switch IDs.
iTunes match is enabled under one of the IDs.
Any help is appreciated.

This ID mess started because I was seeing Apple messages that all IDs had to be email addresses, so I created a second ID. The problem is that some apps and purchases were under one ID, and some under the other ID. now, I never know which ID to log on with, and it takes at least a couple of attempts to log in, where Apple accepts the ID and password.
Also, I have iTunes Match under one of the IDs.

ThinkVision L2251x - Environment Sensing Utility only recognizes one monitor

Hello,
I have a ThinkCentre M90p with two ThinkVision L2251x monitors - one attached by DisplayPort and the other attached by VGA. Both monitors are also attached by a USB cable.
I have recently installed the Environment Sensing Utility, and it works fine on the monitor using DisplayPort, but it doesn't work at all on the other monitor.
I am able to use the cameras and microphones on both monitors using other software.
My OS is Windows 7 Professional, SP1.
I'd appreciate any suggestions.
Thanks!

i had the same problem, i solved it by buying a more higher end "hdmi to vga" wire, i 1st bought a cheap conversion wire "hdmi to vga" from a slow boat from china via Amazon and it didn't work on my macbook but seems to be working well on my windows laptop.
so i bought another conversion wire via Amozon "hdmi to vga" from a company called Sewell Quirts in a 10' version.... now my mac mirrors or extend my laptop monitor, hope this helps.
and its not a "file" issue like everyone else says in here.
and my acer monitor is an older one with only a dvi and vga inputs.... using it to extend my 2014 macbook pro retina.

I have both a 1st generation AppleTV and 2nd Generation AppleTV, and my iTunes seems to only recognize one at a time - has anyone else had this problem - can you only use one at a time?

Is this a design flaw? Since the 1st Generation has a hard drive (140GB). If both are on, only the 1st Gen get recognized. I would think you could use both at the same time..... Help!

Welcome to the Apple Community.
Yes iTunes should work with them all together. Do they have different names, are they on the same network, have you noticed any other problems.

Icloud contacts only recognize one account

I have two ipod touches and textfree accounts for both. before using icloud the contacts from facebook always seperated, but now all contacts are from the first account. any way to remedy this???

After about 10 deleting of my iCloud account and then relogging in on my iPhone it finally synced.

Only one CPU core recognized [solved]

For some reason the kernel only recognizes one CPU core out of two. I'm not completely sure at which kernel upgrade it disappeared but it is gone in 2.6.36 and 2.6.37. I know it was still there in september 2010 and earlier. I'm using a x86-64 kernel.

Motherboard is: Gigabyte MA770T-UD3P. I use the latest bios.
I have tried adding the kernel options "acpi=off noacpi apic=off noapic" as to the suggestion of a ubuntu bug report in launchpad but it didn't help. I also disabled ACPI in the bios but I'm still limited to one cpu core.
Any ideas?
[SOLVED]
I just doublechecked the BIOS settings and it had the CPU Core Control set to manual and one core was disabled. I set it to auto again and now both cores are recognized correctly. I don't recall ever touching this setting but at least it works now. Maybe a bios update actually changed the setting or (more probable) a friend of mine.

I have 8 gb on my macbook pro, but it sometimes only recognizes 4 gb. Whats going on?

I have 8 gb on my macbook pro, but it sometimes only recognizes one of the banks and thus only 4 gb. I was about to open my Macbook Pro mid 2010 2.66 up but it went back up to 8 gb of ram.
I also noticed that the macbook would go to sleep and not wake up again, sometimes. Not sure if this is related.
I did the usual, resetting the PRAM and the other thing with "shift control option." It didn't work and kept on saying 4 gb.
I woke up this morning ready to break open the mac when it read 8 gb. Great! But the **** is going on. Is that memory slot loose?
My google search and search through these forums were useless, no solutions. One guy tried changing his memory into the two banks, no difference. Sometimes it recognizes bank 1 sometimes it doesn't. Another put his ram in another computer, it's not the ram. Someone suggested the motherboard, then someone said "no way" for some arcane reason.
The only solution that seamed viable was going back to snow leopard, the last great OS. Im on mountain lion, not to shabby, but no leopard.
Problem is that I am out of warranty.
Any suggestion would be helpful.

why don't you try this:
open the back of your Macbook - if you're technically capable...
take the ram out, clean it up with a pencil eraser - blow it out - put them back in, slowly and in a slight angle until they lock into place - make sure they are seated correctly...
restart your macbook - if the same bank is still not detecting - then the issue is your RAM slot...
good luck
